Myocardial remodeling is a common cardiac response to various pathological stimuli and may refer to changes in structure and function (structural remodeling) or electrophysiologic properties (electrical or ionic remodeling) [1–3]. Such disease-induced changes of tissue composition and architecture or function occur in both the atrium and/or the ventricle, and appear to progress steadily in a vicious cycle that, if not halted, eventually causes death of the patient [1]. Structural remodeling itself has a substantial influence on cardiac conduction properties [4]. In particular, the development of conduction inhomogeneities, including areas of slow conduction and conduction
